anonymous · Answer

lets call the number of graphite clubs $x$ so the number of steel clubs must be $16-x$ (since the total is 16\)

anonymous · Answer

then you know the total of graphite clubs was 
$$549x$$ and the total money from steel ones is $339(16-x)$ and you also know that it has to add up to $7314$ so you can set 
$$549x+339(16-x)=7134$$ and solve for $x$

anonymous · Answer

x=9 and that would be the final solution?
